Feature/refactor to use less `lodash`

In API space only. As the project targets ES2022, some built-ins can be
used.

When ES2024 is available (node 22), stuff like Ojbect.groupBy will be
available.

I'm also tempted to reduce the use of `_.sortBy` as it can be replaced
by the standard library. I have no idea why lodash is used.
